about

achavi - Augmented OSM Change Viewer [attic]

Displays OpenStreetMap changes based on the Overpass API
Augmented Delta (adiff) query and the
Augmented Diff format.
Tested on Firefox and Chrome; older Internet Explorer and mobile not supported.

This is an early alpha version and many features are missing, like better relation support, changeset
information, textual list and/or summary of changes and performance optimization. Also expect to find bugs.
